Abstract

High-spin states in Cs124 were populated in the Ni64(Ni64,p3n) reaction and the Gammasphere detector array was used to measure γ-ray coincidences. Both positive- and negative-parity bands, including bands with chiral configurations, have been extended to higher spin, where a shape change has been observed. The configurations of the bands before and after the alignment are discussed within the framework of the cranked Nilsson-Strutinsky model. The calculations suggest that the nucleus undergoes a shape transition from triaxial to prolate around spin I≃22 of the positive-parity states. The alignment gain of 8â.,, observed in the positive-parity bands, is due to partial alignment of several valence nucleons. This indicates the absence of band crossing due to paired nucleons in the bands.

Abstract

© 2015 American Physical Society. Excited states in Lu167 were populated in the Sb123(Ca48,4n) reaction at 203 MeV and decay γ rays measured using the Gammasphere spectrometer array. Two triaxial strongly deformed bands were identified previously and interpreted as zero- and one-phonon wobbling excitations. As a result of more extensive band search, the level scheme has been considerably extended to include ten new rotational bands and some 630γ-ray transitions. A number of interband linking transitions were revealed, so that all but two bands could be connected with each other. Configurations are proposed for all new bands based on measured observables, with the help of cranked shell model calculations. A γ-ray sequence, previously suggested as a triaxial strongly deformed band based on quasiparticle excitations coexisting with the wobbling excitation in the triaxial potential well, has now been determined to be a signature partner of a coupled band, associated with a normal deformed five-quasiparticle configuration. The possibility of two new bands being associated with triaxial deformation is discussed.

Abstract

New positive-parity states, having a band-like structure, were observed in 105Ru. The nucleus was produced in induced fission reaction and the prompt gamma-rays, emitted from the fragments, were detected by the EUROBALL III multi-detector array. The partial scheme of excited 105Ru levels is analyzed within the Triaxial-Rotor-plus-Particle approach.

7. Observation of Positive-Parity Bands in $^{109}$Pd and $^{111}$Pd: Enhanced $��$-Softness

Abstract

The neutron-rich nuclei $^{109}$Pd and $^{111}$Pd were produced as fission fragments following the $^{30}$Si + $^{168}$Er reaction at 142 MeV. Using the identification based on the coincidences with the complementary fission fragments, the only positive-parity bands observed so far in $^{109}$Pd and $^{111}$Pd emerged from this work. A band, built on top of the 5/2$^+$ ground state exhibiting $��I$ = 1 energy-level staggering, was observed in each of these nuclei. Both nuclei of interest, $^{109}$Pd and $^{111}$Pd, are suggested to lie in the transitional region of Pd isotopes of maximum $��$-softness. The ground states of both nuclei are predicted by TRS calculations to be extremely $��$-soft with shallow triaxial minima. The first crossing in the new bands is proposed to be due to an alignment of $h^2_{11/2}$ neutrons.

Abstract

The level structure of 60140Nd80 has been established up to spin 48 by in-beam γ-ray spectroscopy by use of the Zr96(Ca48, 4n) reaction. High-fold γ-ray coincidences were measured with the EUROBALL spectrometer. Twelve new rotational bands have been discovered at high spins. They are interpreted as being formed in a deep triaxial minimum at 2 0.25 and γ 35°. Possible configurations are assigned to the observed bands on the basis of configuration-dependent cranked Nilsson-Strutinsky calculations. © 2005 The American Physical Society.

Abstract

The gamma-ray spectra from the decay of the GDR in the compound nucleus reaction 18O+28Si at bombarding energy of 105 MeV have been measured in an experiment using the EUROBALL IV and HECTOR arrays. The obtained experimental GDR strength function is highly fragmented, with a low energy (10 MeV) component, indicating a presence of a large deformation and Coriolis effects. In addition, the preferential feeding of the highly-deformed band in 42Ca by this GDR low energy component is observed., Comment: 6 pages, 2 figures, Proceedings of the Zakopane2004 Symposium, to be published in Acta Phys.

Abstract

The intrinsic width of (multiparticle-multihole) compound states is an elusive quantity, of difficult direct access, as it is masked by damping mechanisms which control the collective response of nuclei. Through microscopic cranked shell model calculations, it is found that the strength function associated with two-dimensional gamma-coincidence spectra arising from rotational transitions between states lying at energies >1 MeV above the yrast line, exhibits a two-component structure controlled by the rotational (wide component) and compound (narrow component) damping width. This last component is found to be directly related to the width of the multiparticle-multihole autocorrelation function.

Abstract

The decay-out spectrum of the superdeformed yrast band in 192Hg comprises a quasicontinuum, from which about 50 weak discrete transitions of energy between 1 and 3.2 MeV are resolved. The fluctuations of the one-dimensional quasicontinuum spectrum are studied with the fluctuation analysis method, which shows that of the order of a few thousand different transitions are available in the first step of the decay-out cascades. The experimental effective number of transitions is compared to schematic theoretical calculations.

Abstract

International audience; The Euroball-IV \gamma -detector array, equipped with the ancillary charged particle detector array DIAMANT was used to study the residues of the fusion reaction $^{64}$Ni + $^{64}$Ni \Rightarrow $^{128}$Ba at E_{beam} = 255 and 261 MeV, in an attempt to reach the highest angular momentum and verify the existence of predicted hyperdeformed rotational bands. No discrete hyperdeformed bands were identified, but nevertheless a breakthrough was obtained through a systematic search for rotational ridge structures with very large moments of inertia J(2) \ge 100 {\mathchar h}^2 MeV^(-1), in agreement with theoretical predictions for hyperdeformed shapes. Evidence for hyperdeformation was obtained by charged particle + \gamma -ray gating, selecting triple correlated ridge structures in the continuum of each of the nuclei, $^ {118}$Te, $^{124}$Xe and $^{124,125}$Cs. In 7 additional nuclei, rotational ridges were also identified with J(2) = 71--77 {\mathchar h}^2 MeV^(-1), which most probably correspond to superdeformed shape. The angular distributions of the emitted charged particles show an excess in forward direction over expectations from pure compound evaporation, which may indicate that in-complete fusion plays an important role in the population of very elongated shapes.

Abstract

In recent attempts to search for exotic shapes, hyperdeformation (HD), and Jacobi transitions in Hf, Ba, Xe, Sn and Nd nuclei, ridge structures presumably originating from nuclei of very elongated shapes have been observed in 126Ba, with Gammasphere (GS) and in 126Xe, with Euroball-IV (EB-IV). After the promising results from GS, a second experiment in 126Ba followed at EB-IV, taking advantage of the use of the BGO Inner Ball (IB) for selecting the highest spins. The decay of the Giant Dipole Resonances (GDR) is also studied, and the analysis in progress. The Quasi-continuum transitions in the Jacobi region, show a significant decrease in energy for both 126Ba and 126Xe, compared to the Thomas-Fermi- and the LSD model predictions. Similar effects were recently found for other nuclei by Ward et al.

Abstract

Matière Nucléaire; International audience; The ultimate search for hyperdeformation (HD) at high spins with the EUROBALL spectrometer was performed for 126Ba as a hyper long (HLHD) experiment. The DIAMANT ancillary detector was used to tag \gamma -rays in coincidence with the emitted light charged particles. Using \gamma -energy correlation methods, the particle--xn-\gamma data have been analysed to search for hyperdeformed structures in the corresponding residual nuclei. Data in coincidence with one \alpha particle indicate the presence of normal deformed collective bands up to very high spins and the possible occurrence of HD-like ridge structures in 122Xe.

Abstract

International audience; The \gamma -decay from the warm rotation in the transition region between order and chaos is studied in the superdeformed (SD) nuclei 151Tb and 196Pb, using the EUROBALL IV array. A number of observables, testing the decay dynamics in the SD well, are compared with predictions from a Monte Carlo simulation of the \gamma -decay based on microscopic calculations of discrete levels and decay probabilities. Agreement with the data is found only assuming an enhancement of the B(E1) strength around 1 MeV by a factor of 10-100, which is consistent with the evidence for octupole vibrations in both mass regions. The work shows the relevance of \gamma -spectroscopy in the order-to-chaos regime to highlight specific nuclear structure effects.

Abstract

The $\gamma$ decay in the quasi-continuum is used as a probe of nuclear structure properties in thermally excited nuclei. The experimental analysis is performed on high-statistics EUROBALL data on $^{163}$Er, and the results are compared to band mixing calculations for this nucleus. Two topics are investigated. First, a direct experimental measurement of the rotational and compound damping width ($\Gamma_{rot}$ and $\Gamma_{\Mu}$) is given. From a line-shape analysis of $\Gamma-\Gamma$ coincidence spectra values of 200 and 20 keV are obtained for $\Gamma_{rot}$ and $\Gamma_{\Mu}$, respectively, in the spin region I $\approx$ 30–40$\hbar$, in good agreement with theory. Secondly, the validity of the selection rules associated with the $K$-quantum number are investigated as a function of the internal energy $U$ above yrast. $K$-selection rules are found to be obeyed in the decay along discrete unresolved rotational bands up to U$\approx$1.2 MeV, while in the interval U$\approx$1.2–2.5 MeV, where the order-to-chaos transition is expected to take place, selection rules are found to be only partially valid.
